Abstract: PURPOSE:To realize a magnetic recording card provided additionally with a security function by providing magnetic bars comprising a soft magnetic material on a magnetic recording part of a magnetic recording card, in a pattern of confidential information characteristic of the card. CONSTITUTION:This magnetic recording card comprises a second layer on a magnetic recording part, the second layer comprising a layer 3 containing a soft magnetic material and a layer 4 not containing any soft magnetic material. The magnitude of a magnetic field leaking to the surface from a magnetized magnetic layer of the magnetic recording part, in the areas of the layer 3 is about two times that in the areas of the layer 4. The magnitude of the leakage magnetic field is read as the magnitude of a reproduction output voltage, whereby the presence of magnetic bars constituted of the soft magnetic material is verified, and the information recorded in the form of the magnetic bars is read as a magnetic record output. When a magnetic record of a magnetic recording card obtained by duplication of the magnetic recording card in which the information is recorded by the above method is again written into a magnetic recording card, the duplicate magnetic recording card does not have the confidential information recorded in the original magnetic recording card as the magnetic bar pattern.

Title: Treatment of communication trouble in operating engine-driven heat pump type air conditioner
Inventor: SUZUKI YUTAKA
IPC: F25B27/00
Filed: 1991-09-05
Abstract: PURPOSE:To make it more convenient to use an engine-driven heat pump type air conditioner by enabling it, when trouble has occurred in its system of communication, to stop the operation once and, when it is discovered that the trouble has been removed, to automatically resume the operation. CONSTITUTION:An engine-driven heat pump type air conditioner stops operating when trouble has occurred in the communication between a remote control 3 and an indoor unit 2 or between the indoor unit 2 and an outdoor unit 1. When the trouble in communication which has caused the apparatus to stop operating is a transient phenomenon which is due to a noise 6 and has spontaneously passed away and it has become clear that the system of communication has been restored to its normal condition, the indoor unit 2 signals to the remote control 3 the recovery of the normal condition in the communication and restores itself to the normal condition. The outdoor unit 1 also restores itself to the normal condition and stands by for a command from the indoor unit 2 to resume the operation. Thus, as the noise 6 passes away, the apparatus is made ready to operate and the operation is automatically resumed. This method makes the air conditioner more convenient to use.
